The length of fire protection painting can be freely adjusted as needed. Since the assembly and disassembly of the fire protection structure are convenient, the fire protection structure can be easily maintained.

Description

FIELD OF THE INVENTION [0001] The present invention relates to a prefabricated fire protection structure,

FIELD OF THE INVENTION The present invention relates to a prefabricated fireproof structure and a method of assembling the same, and more particularly, to a prefabricated fireproof structure and a method of assembling the same which are installed to prevent fire from diffusing when a ship or an offshore structure is fired.

In general, passive fire protection (PFP) is intended to delay the direct delivery of the flame for a certain period of time and is being applied to the main structure rather than to the entire vessel or offshore structure.

Such fireproofing structures use refractory paints, and PFP firepolishing paints are mainly used as refractory paints.

The PFP (Passive Fire Protection) refractory coating is coated on the bulkhead, deck, and steel structure (Bulkhead, Deck) to cope with the oil explosion fire of the ship or the marine or offshore structure. Thereby protecting the structure.

At this time, PFP construction using PFP refractory paint is applied in order to prevent sudden drop in strength of main structures in case of fire in marine or land structure, to secure evacuation time, to prevent spread of fire and to protect people and property.

In other words, the fire-fighting structure allows the PFP construction to be carried out on the main support or steel wall, which is the main structure of land and marine structure, so that the support force against the main support or steel wall can be secured for a certain period even if a fire occurs. So as not to be sharply dropped by the flame.

On the other hand, fire protection structures are installed not only on bulkheads, decks and steel structures but also on cable trays. The fire protection structure of such a cable tray constructs a part of the support as an arson structure, which is also referred to as "PFP Coat-back".

1 is a cross-sectional view briefly showing a state in which PFP Coat-back is applied.

As shown in Fig. 1, PFP Coat-back is used to delay the transfer of heat from the first member 1 not subjected to the PFP coating to the second member 2 coated with PFP, 1) by a predetermined length.

That is, one side of the first member 1 is coated with PFP by a predetermined length in order to delay the transmission of heat to the second member 2.

As shown in Fig. 1, the PFP coating is made of a length indicated by a hermetic line from the front end of the first member 1 to the right side of the drawing, thereby delaying the heat of the second member 2 from being transmitted to the first member 2 .

On the other hand, NORSOK's regulations require that PFP Coat-back is required if the cross-sectional area is over 1,000 mm2. In particular, the cross-sectional area of cable tray support may exceed 1,000 mm2.

Accordingly, PFP Coat-back coating is also required for the support of the cable tray, and there is a problem that PFP Coat-back coating can not be performed depending on the structure or shape of the support in the support assembly of such a cable tray.

When the cross-sectional area of the member is more than 1,000 mm 2, the PFP coat-back coating is indispensable. However, there is a problem that the PFP coat-back can not be applied to the cable tray in which the H- beam and the H- .

As shown in FIG. 1, a support member (not shown) is installed in a support provided on a full-length cable tray, and the support of the full-length cable tray is brought into contact with the fixing member and assembled with bolts.

Accordingly, if the PFP Coat-back is first performed on the fixing member, the support can not be installed by the following operation. Therefore, the support is first assembled to the fixing member, and then the PFP Coat-back is applied to the fixing member and the support in the subsequent process.

However, PFP Coat-back can not be applied to subsequent processes depending on the thickness, length, shape, and so on of PFP Coat-back. In addition, this PFP coat-back has a problem in that it does not satisfy the NORSOK specification.

For example, Patent Document 1 below discloses a method of constructing a PFP for an offshore structure.

The PFP construction method of an offshore structure according to Patent Document 1 is a method of constructing a PFP on a steel wall or a ceiling of an offshore structure by fixing a PFP pin and an insulation pin on a surface of a steel wall or a ceiling, The contamination prevention member is installed so as not to be exposed.

Korean Patent Publication No. 10-2014-0078950 (published on June 26, 2014)

However, according to the conventional method of PFP construction in an offshore structure, there is an advantage that the insulation pin is not contaminated by the PFP coating by installing the contamination preventing member so that the PFP coating is not applied to the insulation pin. However, There is a problem that PFP coat-back coating can not be performed, and there is a problem in that it can not satisfy NORSOK's regulations.
